Abstract
A device for opening a sealed container, the device comprising, a first arm having a proximal and distal end, a second arm having a proximal and distal end, a cutting device, and at least one guiding device, wherein the guiding device is disposed on one of the first and second arms. Furthermore, the guiding device is adapted to receive a double seam of a sealed container, thereby preventing the device from slipping.
Claims19
A cutting tool, comprising:
- a first elongated element including an arcuate portion adjacent a first end, a handle portion adjacent a second end, and a depressed region including an aperture formed therein, said depressed region disposed at said first end;
- a second elongated element including an arcuate portion adjacent a first end, a handle portion adjacent a second end, and a depressed region including an aperture formed therein, said depressed region disposed at said first end;
- a pin extending through said apertures at said first ends of said elongated elements, wherein said depressed region of said first elongated element is configured to rotatably receive said depressed region of said second elongated element, when assembled said first and second elongated elements reside within a single plane, said first and second elongated elements pivotally coupled together by said pin;
- a cutting blade rotatably disposed upon a first end of said pin;
- a handle rotatably associated with a second end of said pin, wherein said handle element is configured to rotate independent of said cutting blade;
- a first guide element rotatably positioned on said first elongated element;
- and
- a second guide element rotatably positioned on said second elongated element, wherein said first and second guide elements are absent any cutting edge.

A cutting tool configured for cutting open oil filters, comprising:
- first and second elongated elements each including a handle portion and an arcuate portion, said first and second elongated elements further including a first and second surface, said elongated elements pivotally coupled together at a pivot point with a pivot pin, said pivot point located adjacent said arcuate portions;
- a removable cutting blade associated with said pivot pin, wherein said cutting blade is disposed adjacent to the first surface of the first and second elongated elements;
- and
- first and second guides rotatably attached to said first and second elongate elements, said first and second guides projecting from said first surface, and said first and second guides being absent of any cutting edge.
